NEAR TERM [Through Tonight].
An area of low pressure was located across the northern Gulf early this morning, and moisture was increasing from the west. This was bringing in stratocumulus clouds in the 3.5-5kft range across interior southeast Georgia and the Suwannee Valley. Mostly clear skies were noted elsewhere, with some Patchy fog noted in Duval County. The cloud cover was keeping temperatures in the 50s across interior southeast Georgia, with 40s elsewhere except in the 50s at the beaches.
The area of low pressure over the Gulf is forecast to weaken and sink south to southeastward as high pressure builds east of the Appalachians today. Low to mid level moisture is forecast to move into the Suwannee Valley in the afternoon, and an isolated shower cannot be ruled out. Highs today will be near normal in the upper 60s to lower 70s.
An inverted trough east of the state of Florida and strong high pressure building over the Mid Atlantic and down the Carolinas will briefly create a tight pressure gradient tonight over the regional waters, and a few coastal showers are possible late in the night at the northeast Florida beaches. Overnight lows will be warmer in the mid 40s to near 50 across interior southeast Georgia, the low to mid 50s across interior northeast Florida, and mid 50s to around 60 at the beaches.
SHORT TERM [Sunday Through Monday].
The influence of high pressure over the region will lessen at the start of the oncoming week, with a southwesterly flow developing ahead of the approaching cold front from out of the northwest. There is a mild chance for showers to develop along the easternmost counties of the forecast area on Monday. Maximum temperatures will increase next week with daily max temps rising into the upper 70s and possible lower 80s on Monday. Overnight low temperatures will have a similar rise with temps rising from out of the 50s on Sunday night into the upper 50s and lower 60s.
LONG TERM [Tuesday Through Saturday].
Prevailing flow will strengthen out of the southwest ahead of the approaching cold front, moving in from out of the northwest. Forecast models are predicting the front to stall out over Georgia, resulting in a prolonged period of convection over northeast Florida and southeast Georgia lasting into next weekend along the frontal boundary. Above average temperatures on Tuesday are expected to drop as the frontal boundary approaches, with temps dropping from out of the lower 80s on Tuesday down into the upper 50s and lower 60s for the remainder of the week, with cooler temperatures occuring in counties behind the frontal boundary. Overnight low temperatures will also cool with the approach of the front, with min temps ranging from the upper 30s to the lower 50s with the coolest temps occuring over inland southeast Georgia.
AVIATION. [Through 06Z Sunday]
Patchy fog is possible at the Duval County TAF sites this morning. Light winds will prevail overnight, with winds becoming northeast 5-10 knots during the day as high pressure sinks south southwestward east of the Appalachians. A couple showers are possible near KGNV in the late afternoon, but probabilities are too low to mention.
The pressure gradient will begin to increase this afternoon and tonight between high pressure building east of the Appalachians and an inverted trough east of the state of Florida. Brief Small Craft Advisory conditions are possible tonight over the offshore southeast Georgia waters. Scattered showers are also possible over the coastal waters. Surface high pressure will build east of the Mid Atlantic and the inverted trough will lift northward on Sunday leading to lighter winds. The surface ridge axis will remain south of the area through Tuesday. A cold front will push across the waters on Wednesday, and stall near or just south of the waters through the end of the week. Small Craft Advisory conditions are forecast late Wednesday into Friday. Scattered to numerous showers are forecast each day.
Rip Currents: Low risk southeast Georgia today and moderate risk on Sunday. Moderate risk of rip currents northeast Florida beaches this weekend.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
